In my home office, I have a headless server running Windows
Server 2008 with iTunes 8 installed. This machine is where I store all of my music, photos, videos, and other entertainment related files. The interesting thing is that I also use this server to wirelessly broadcast my iTunes music digitally to my kick-ass home studio setup (a Benchmark DAC1, Coleman Audio M3, Quested Powered F11As, and a REL Subwoofer). The setup that I am about to describe should work equally as well for those of you who have any kind of audio playback equipment that has an optical audio input.
